I have a 740 that started running horrible and then started leaking fuel from air inlet. Decided I'd attempt the rebuild since my mechanic was swamped. Everything came apart fine
and cleaned up nice. Bought a TSC kit (I know) and float. First attempt after reinstalling on tractor i didn't get any fuel into carb. Found the new valve and seat would stick
closed. I cleaned and reused old valve and seat (spring type). Second attempt the tractor start but I couldn't get the RPMs to come down. I had more throttle response using the
choke than I did with the throttle lever. Then I remembered I had the required "extra" new parts - a white felt and rubber bushing left over in the kit. Sprayed some carb cleaner
around throttle shaft and RPMs went up. Guessing I had an air leak I read the shop manual again then removed carb and put the rubber bushing on the throttle shaft and the felt
bushing on the choke shaft. Third attempt to start the tractor will fire up, run at high RPMs, then stall with it choked, but it won't stay running. This is why I don't like dealing
with the carb, but they seem so simple. Also, I have already cleaned the air cleaner and filled with new oil.
Could someone provide some guidance/suggestions? I have the shop and repair manuals but still can't figure it out.
